Updated October 8, 2026. Quick answer: Generally no, if you qualify for the federal exclusion. The TC-40 instructions start at “Line 4. Federal Adjusted Gross Income”, which leaves out a gain excluded under section 121. Gain above it is taxed at a flat rate; the 2026 withholding guide prints “Multiply line 1 by .0445 (4.45%)”, down from 4.5% for 2025.

| Profit on your main home | Starts from federal adjusted gross income; the pages read print no separate Utah home-sale exclusion |

What the Utah documents say
The 2025 TC-40 instructions begin the computation with “Line 4. Federal Adjusted Gross Income”. Under the federal statute, “Gross income shall not include gain from the sale or exchange” of a principal residence that meets the ownership and use tests, so an excluded gain never enters federal adjusted gross income. That is reasoning from two documents. The instructions print no separate Utah home-sale exclusion, and the Utah pages read never name section 121.
For 2025 the form says “Multiply line 9 by 4.5 percent (.045)”, and the instructions note legislation “lowering the income tax rate from 4.55 percent to” 4.5 percent. For 2026 the Tax Commission’s withholding guide, revised April 2026, prints “Multiply line 1 by .0445 (4.45%)”.
What the federal exclusion requires
Most state answers start here. The statute says “Gross income shall not include gain from the sale or exchange” of property that, during the five years before the sale, you owned and used as your principal residence for periods adding up to two years or more. The limit is “shall not exceed $250,000”, or $500,000 for a husband and wife who make a joint return and meet the statute’s conditions. See CMG’s home sale taxes page and exclusion calculator.
A worked example at a $400,000 gain
An illustration, not a return: a married couple in Utah sells their main home with a gain of $400,000 and meets the federal ownership and use tests. The gain is below the $500,000 joint exclusion, so it is not in federal adjusted gross income and, on the documents read, $0 is taxed by Utah. As a second illustration, computed below, suppose the gain were $600,000. The amount above the exclusion would then be $100,000 and, computed as that excess times 4.45%, the tax at the flat rate would be $4,450, before any other adjustment.
What is collected at the sale
The documents read show no Utah withholding, prepayment or transfer tax on a home sale. That is a gap in what was read, not a statement that none exists; ask the closing agent.
What changes in 2026
Utah: the Tax Commission’s April 2026 withholding guide uses a flat 4.45%, down from the 4.5% in the 2025 instructions.
What the documents do not say
- The pages read never name section 121, so conformity is reasoned from the federal starting point. The 2026 rate comes from the Tax Commission’s withholding guide; the enacted bill text was not archived. No sale-time rule was found. The instructions are for tax year 2025.
Common mistakes
- Using the 4.5% rate printed in the 2025 instructions for a 2026 sale; the 2026 guide prints 4.45%.
- Applying the flat rate to the whole gain; the rate applies to what remains after the federal exclusion.
- Assuming the answer for one state applies to another, or that the state answer changes the federal tax on the sale.
